Serial no. 59.4,77513 This invention relates toembalming instruments, it more particularly relating to an strumentfortheuse of embalmers for asp'1- rating or'withdrawing' morbidfluidsffrom thefbody and injecting the'embalming fluid. In moderninstruments of this character, it'has been the practi'ceto employ amanuallypperated piston with suitable [connections including checkvalves, such an instru ment requiring the e'nflployment of both handsofthe embalmer to perform the necessary operations of aspiratingandinjectin'g.

The object of my inventionis to provide an] 15 instrument of thischaracter so designedthat it-may be readily operated with but one handof the embaliner, leaving theembalmersfother handfree for othernecessary duties.

In the accompanying drawing Fig. 1 is a side-elevation of an instrumentembodying the improvement.

Fig.2 is a view partly in longitudinal sec-- tion and partly inelevation with a portion of the palm rest broken away.

Fig. '3 is an end view. t

Fig. 4L is a slightly enlarged section on the line 4.4 of Fig. 2. V

Fig. 5 isa slightly enlarged section on the line 5-5 of Fig. 1.Referring to the cylinder, 2 and 3 the heads of the cylinder, 4 apiston, 5 .the piston rod which extends through the head 2, and 6 anelongated open finger-piece connectedto the piston rod. The head 3carries valve mechanism and tube connections of a well known kind. Avalve chamber 7 is threaded on a plug 8 which is in turn threaded intothe head 3, this chamher having an injecting nozzle 9 shaped to receivea flexible tube (not shown). The plug. has an annular recess to receivean outwardly opening check valve in the form of a rubber cup-shapedmember 10 which is partially slit adjacent its closed end to form, thecheck valve proper 11. The plug 8 has an aperture 13 forming acommunication between the cylinder and the cup, and the nozzle '9 apassage 9. Y I I A second valve chamber 14 is threaded into 1- the head3 and has threaded into the outer end thereof a plug 15 having a nozzle16 to drawing, 1 represents a receive alt ube (not shown). This plug is7 provided Wltllilll annular recess to'receive a cup-shaped check :valvemember'17 having an inwardly opening valve" proper 18 formed! 1n thesame manner as that described in con-{ nection with the outwardlyopening check" valve. The chamber 14 has an aperture 19 leading to thecylinder and the plug and its nozzle has an aperture20 leading from itsouter end to the interior of the cup-shaped check valve" Theconstruction so fardescribed is of a well known form of injecting andaspirating instrument-land the improve-ments whichT have made thereonwill now beexplaine'd. Surrounding the piston rod 5, and inter posedbetween the head Qand the piston 41s" a coil spring 21 which acts toproject the pieton in the directionofthe head 3. Connected totlie'head 2is'a palm rest {consisting offla' yoke shaped member5thearms 22 and 23'of which have theirffree ends connected with the head 2and theconnecting cross-member 24 of which is provided with rounded palm TFortfe' purpose of compactnessin storing the instrument when not innjse, Ihave pivotally connectedthe arms ofthe yoke-shaped palm restwith thecylinder head 2"inorde'r that the palni res t may be'swung to the dottedline position of The cylinder head 2 has a pair ofoppositelyarranged'trunnions 26am threaded in each is a screw 27; the v,screwf'liaving .a plain" cylindrical portion: upon which an enlargedboss 28 at the end of an arm iof'the palm rest is pivotally mounted.Intorder to yieldably lock the yoke-shaped palm rest in either position,the inner end of each boss is provided with transverse recesses 29adapted toreceive a transversely-extend 90 .ing pin 30 whichis'driveninto the plain cylin drical portion of the screw, and the boss 28 Thisspring act to force the boss toward. the;
